Increase horsepower and add under-hood style with the PERRIN Cold Air Intake.
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.
Eliminating intake restrictions and increasing flow potential allows for faster turbo spooling, reduces turbo lag, and broadens the power band.
PERRIN Intake filter elements use open-cell foam to capture dust and dirt. Washable and reusable, PERRIN foam filter elements can last the life of your vehicle. Foam filter elements offer superior performance with minimal airflow restriction and amazing dust-holding capacity.
Keeping your air filter clean is essential for optimal performance and longevity of your vehicle's engine.
The OEM MAF sensor wiring harness is too short to work with the PERRIN Cold Air Intake. Provided with each kit is a MAF sensor extension. This extension comes with OEM plug ends to relocate the MAF sensor with no compatibility issues.
With a PERRIN Intake system, your car will make a throaty, deep tone on the throttle that is undeniably modified. You will be able to hear your turbo spooling and hear your blow off valve every time it opens, even the stock one.
